1.

CHECK DOOR SWITCHES INPUT SIGNAL

With CONSULT-III

Check door switches ("DOOR SW-DR", "DOOR SW-AS", "DOOR SW-RL", "DOOR SW-RR") in DATA MONI-
TOR mode with CONSULT–III. Refer to 

BCS-15, "DOOR LOCK : CONSULT-III Function (BCM - DOOR

LOCK)"

.

• When any doors are open:

• When any doors are closed:

Without CONSULT-III

Check voltage between BCM connector M18 or M19 terminals 12, 13, 47, 48 and ground.
